Who regulates private investigators in Pennsylvania
Pennsylvania’s Private Detective Act of 1953 (22 P.S. § 11 and following) sets the rules statewide, but each county’s court of common pleas issues licenses for detectives with offices in that county. Procedures and filing fees vary somewhat by county, so contact the clerk of courts where your office will be.
In Lehigh County, for example, applicants file with the Clerk of Judicial Records (Criminal Division) and are interviewed and fingerprinted by the County Detective Division of the District Attorney’s Office.
Pennsylvania PI license types

Carrying a firearm as a Pennsylvania investigator
A Pennsylvania private detective license doesn’t by itself authorize carrying a firearm. Pennsylvania has separate rules for armed security (Act 235 lethal weapons training) and concealed carry. Get advice before carrying on duty.
What a private investigator in Pennsylvania can and can’t do
A PI license is a business license, not police authority. In Pennsylvania, as everywhere in the U.S., private investigators generally cannot:
- Impersonate law enforcement or claim official authority.
- Trespass on private property to watch or photograph someone.
- Obtain bank, phone or other protected records by pretexting, which federal law prohibits.
- Hack accounts, read someone else’s email or install spyware.
- Place a tracking device on a vehicle where state law forbids it.
- Detain or arrest anyone beyond the citizen’s arrest rights every person has.
Recording is a particular trap in Pennsylvania. A 2024 legal summary by the law firm Kilpatrick lists Pennsylvania among the states that require the consent of all parties for at least some recordings of conversations. Never record a conversation you are not part of, and get legal advice before recording calls or private conversations.

Starter gear. A practical starting point for surveillance work is a long-zoom camera such as the Nikon Coolpix P1000 and a pair of binoculars like the Vortex Diamondback HD 10×42. Our private investigator equipment list covers the rest of a starter kit.
